Figure 116 Bandwidth Usage Example
The following figure shows the bandwidth usage with the maximize bandwidth usage option
enabled. The Prestige divides up the unbudgeted 64 Kbps among the rules that require more
bandwidth. If the administration department only uses 32 Kbps of the budgeted 64 Kbps, the
Prestige also divides the remaining 32 Kbps among the rules that require more bandwidth.
Therefore, the Prestige divides a total of 96 Kbps total of unbudgeted and unused bandwidth
among the rules that require more bandwidth.
In this case, suppose that all of the rules except for the administration rule need more
bandwidth.
• Each rule gets up to its budgeted bandwidth. The administration rule only uses 32 Kbps
of its budgeted 64 Kbps.
• Sales and Marketing are first to get extra bandwidth because they have the highest
priority. If they each require 48 Kbps or more of extra bandwidth, the Prestige divides the
total 96 Kbps total of unbudgeted and unused bandwidth equally between the sales and
marketing departments (48 Kbps extra to each for a total of 112 Kbps for each) because
they both have the highest priority level.
• R&D requires more bandwidth but only gets its budgeted 64 Kbps because all of the
unbudgeted and unused bandwidth goes to the higher priority sales and marketing rules.
• The Prestige does not send any traffic that is not defined in the bandwidth filters because
all of the unbudgeted bandwidth goes to the rules that need it.
